Top 10 agencies with the most Facebook fans

The White House currently has more fans than the Washington Redskins -- Facebook fans, that is.

As young people start using Facebook as their primary communication tool, look for more agencies to experiment with social media for interacting with citizens.

White HouseFans: 327,592A well-traveled site, as to be expected, the White House's Facebook page has plenty of information on administration doings and links to presidential appearances and statements — not to mention lots and lots of comments.

Marine CorpsFans: 83,144The Marines' site is hugely popular — but staid and quiet following the Marines’ clampdown on Facebook and other social media earlier this year.

ArmyFans: 49,416Probably the most heartfelt of government Facebook sites, the Army’s far-flung members and their families can connect with one another and share stories and experiences.

CDCFans: 21,257The Centers for Disease Control seems to have successfully created an engaged and voluble audience while working to fulfill its mission of providing credible, science-based health information.

State DepartmentFans: 16,386The department offers lots of information about Secretary Hillary Clinton’s travels and other diplomatic ventures, in addition to voluminous links to embassy pages. But discussion areas are surprisingly quiet.

NASAFans: 7,768NASA provides an eclectic mix of items pointing to official announcements, with some offbeat stuff thrown in, and a talky fan base of knowledgeable — and sometimes scary — science nerds.

NASA JPLFans: 6,536NASA’s Jet Propulsion Laboratory is the space agency’s center for robotic missions to the planets and beyond, a natural attraction for an energetic audience that isn’t far behind the agency’s main site.

Library of CongressFans: 6,520The hugely informative site about Library events and its collections is devoid of any public feedback and interaction.

Air ForceFans: 3,011A recently created site, the Air Force's Facebook site seems destined for great things based on the reactions it has already received.

Environmental Protection AgencyFans: 2,608It carries a lot of the EPA’s announcements, but it’s also actively trying to build a community among the environmentally minded public.
